MSN class ver 2.0 by Tommy Wu, Ricky Su
License: GPL

You can find MSN protocol from this site: http://msnpiki.msnfanatic.com/index.php/Main_Page

This class support MSNP15 for send message. The PHP module needed:

MSNP15: curl pcre mhash mcrypt bcmath

Usually, this class will try to use MSNP15 if your system can support it, if your system can't support it,
it will switch to use MSNP9. But if you use MSNP9, it won't support OIM (Offline Messages).
